sortKeysRecursive(input, [options])

input

Required
Type: array|object

options

compareFunction

Examples

ignoreArrayAtKeys and ignoreObjectAtKeys

 
const options = {
  ignoreArrayAtKeys: [ // Don't sort the Array at the specified keys, if any.
    'b'
  ],
  ignoreObjectAtKeys: [ // Don't sort the Object at the specified keys, if any.
    'a'
  ]
}
 
const input = {
  a: { // This Object will not be sorted.
    a: 'a',
    b: 'b',
    c: 'c',
    d: ['a', 'c', 'b']
  },
  b: ['a', 'c', 'b'], // This Array will not be sorted.
  d: ['a', 'c', 'b']
}
 
const output = sort(object, options)
 
console.log(output)
 
// {
//   a: {
//     a: 'a',
//     b: 'b',
//     c: 'c',
//     d: ['a', 'c', 'b']
//   },
//   b: ['a', 'c', 'b'],
//   d: ['a', 'b', 'c']
// }

compareFunction

You can pass a custom sort function as compareFunction. This function is passed to Javascript sort(), that sorts in alphabetical order by default. The custom function should return zero, a negative or positive value:

var reverseAlphabeticalSort = function (a, b) {
  return a < b
}
 
var options = {
  compareFunction: reverseAlphabeticalSort
}
 
var object = {
  a: {
    a: 0,
    c: ['c', 'a', 'b'],
    b: 0
  },
  c: 0,
  b: 0
}
 
var output = sort(object, options)
 
console.log(output)
 
// {
//   c: 0,
//   b: 0,
//   a: {
//     c: ['c', 'b', 'a'],
//     b: 0,
//     a: 0
//   }
// }
